The heating assembly includes a second set of pipelines that longitudinally covers at least a portion of the head of the tank.

Abstract: A method for treating polytetrafluoroethylene (PTFE) in its reactor latex form to produce a dry submicron PTFE powder that remains stable without rheology modifiers, surfactants, wetting agents, pH adjusters or other stabilizing additives. Reactor latex PTFE formed during an emulsion polymerization process can be irradiated, with an electron beam or gamma rays, during or after the polymerization to form a product where the dry submicron PTFE powder is free-flowing, tends not to self-agglomerate and tends not to dust into the air upon handling so that the PTFE is readily dispersible when placed in a desired application system or medium.

Abstract: A method for producing submicron polytetrafluoroethylene (“PTFE”) powder in a free-flowing, readily dispersible form. The irradiated PTFE starting material is placed in a desired solvent and undergoes grinding until the PTFE particles reach submicron size. The submicron particles are subsequently recovered from the solvent and dried to form a powder that may have particles less than 1.00 ?m in size. The dry PTFE powder may then be readily dispersed to submicron size into a desired application system. The submicron PTFE powder of this method is free-flowing, readily dispersible in various application systems, tends not to “dust” or self-agglomerate. Improved aqueous and organic dispersions of submicron PTFE particles may also be formed that display increased stability and require much less agitation than other processes of forming such dispersions. Such improved PTFE dispersions may be formed with or without the addition of surfactants, wetting agents, rheology modifiers, pH-adjusting agents, and the like.

Abstract: The present invention provides compositions that are capable of being dispersed in a target medium. The compositions include characteristic use particles entrapped within a physical entrapment phase, wherein the physical entrapment phase is dispersible in the target medium. Accordingly, the compositions of the present invention physically prevent the agglomeration or self-association of the characteristic use particles. Also disclosed are processes for manufacturing compositions that are capable of being dispersed in a target medium.

Abstract: This invention is a process for improving the rheological properties of oil well drilling fluids particularly useful for oil-based invert emulsion types of drilling fluids. The process is particularly useful when drilling in deep water from an off-shore drilling rig. The new process uses as a rheological viscosifier, for such fluids, a composition which is a mixture of organoclays and castor wax and/or castor was type rheological additives, which when added to a drilling fluid at from about 0.5 and 5% by weight, creates an inventive drilling fluid compositions less sensitive to the variety of different and varying, very hot and very cold temperatures found in the drilling hole, and in the long stem of drilling pipe. The present invention also relates to the discovery of oil based invert emulsion drilling fluids that exhibit greater efficiency and provides more stable drilling fluid viscosity and anti-settling performance over varying temperatures when compared to conventional fluids containing organoclays.

Abstract: Quaternary ammonium compositions are described which are made in diluents based on vegetable oil such as soya bean oil. Such diluents remain as diluents in the final product and generally have a vapor pressure of 1 mm of Hg or less at 25.degree. C., and are liquid at ambient temperature. The liquid quaternary ammonium compound/diluent compositions have low toxicity and low volatile organic compound emission rates and high flash points, and can be tailored to particular applications. Such applications include use in fabric softeners, as cosmetics ingredients, deinking additives, surfactants, and reaction materials in the manufacture of organoclays.

Abstract: The present invention relates to improved thickening compositions, often referred to as Theological additives, used to provide viscosity control, flow, leveling and other rheological properties to clear aqueous systems such as automotive clear-coat paints and coatings. The invention hereof involves the synthesis of a new family of Theological additives by combining, through a reaction process, chemicals used to make specified polyurethane polymer compositions. These novel copolymers provides the good flow and leveling and gloss retention that polyurethane associative thickeners impart to water-based systems, without the loss of clarity that such polymers have caused in the past. Levels of the rheological thickening composition, varying between about 0.01% and about 10%, based on the total weight of the system to be thickened, have been found to be useful to create novel clear aqueous systems containing such thickening compositions.

Abstract: The invention involves biopolymer/oil suspension compositions for the oil service industry, most particularly drilling and completion fluids, which provide such fluids a variety of desirable properties. Biopolymers include water soluble polymers and water swellable polymers. Such biopolymer/oil suspension compositions are essentially mixtures of biopolymers such as cellulosics in an oil medium with a specific anti-settling additive. The invention is particularly directed to providing enhanced anti-settling properties to such biopolymer/oil compositions; that is, the ability of the biopolymer/oil composition to retain the biopolymers in suspension prior to the composition being introduced into drilling and completion fluids. The invention in one embodiment is described as a liquid biopolymer-in-oil additive compositions for use in aqueous-based completion fluids, containing an agent comprising: a) one or more polyamides, and b) hydrogenated caster oils including castorwax.
